"Is it true?" or "Does it true?" [closed]

I always get confused about:

• Is it true?
• Does it true?

Where and when should I use one or the other? In other words, when should I pose a question using is and when should I pose it using does?

Solution 1:

You'll use "Does it x" when "x" is a verb (action word). Use "is" otherwise.

Solution 2:

"Is it true?" is an appropriate rejoinder to the statement "His testimony is very convincing!" An appropriate response would be, "[But] is it true?"

"Does it true" is not ever used in English. The following sentence, is, however:

"Does his testimony ring true?"

In other words, does the person's testimony sound true. The word "ring" suggests a bell that rings clearly and distinctly; it rings true. Truth can ring true. By the same token, however, it can also ring untrue or false. ("To ring false" is not a saying in American English, by the way.)

Some people are better liars than others, so one needs to be careful when trying to "read" people.

Solution 3:

"Does it true ..." is just an incorrect use of the phrase "Is it true ..." and seems to be popular in slang/ teen lingo.

Does it true is wrong, ungrammatical in formal writing and does not mean 'is it true'.

Fun:

• I heard that the [separated] memory space will be put into the coming Java SE 8, does it true?

• My dictionary says me that "throw off the scent/track" has an identical meaning. So, does it true or the answer with the "scene" is not correct?

• … does it true that validome (xhtml) is more strict (up to date) than w3c x/html validation?
